PVM(1PVM) PVM Version 3.4 PVM(1PVM)
NAME
pvm - PVM version 3 console
SYNOPSIS
pvm [ -options ] [ hostfile ]
DESCRIPTION
Pvm is a stand alone PVM task which allows the user to interactively query and modify the virtual machine. The console can be started and
stopped multiple times on any of the hosts in the virtual machine without affecting PVM or any applications that may be running.
When started pvm determines if PVM is already running and if not automatically executes pvmd3 on this host, passing pvmd3 the command line
options and host file. Thus PVM need not be running to start the console. Once started the console prints the prompt:
pvm>
The following console commands are available:
add hostname(s) - Add hosts to virtual machine
alias - Define/list command aliases
conf - List virtual machine configuration
delete hostname(s) - Delete hosts from virtual machine
echo - Echo arguments
export - Add environment variables to spawn export list
halt - Stop pvmds
help [command] - Print helpful information about a command
id - Print console task id
jobs - List running jobs
kill task-tid - Terminate tasks
mstat host-tid - Show status of hosts
ps -a - List all PVM tasks
pstat task-tid - Show status of tasks
quit - Exit console
reset - Kill all tasks
setenv - Display/set environment variables
sig signum task - Send signal to task
spawn [opt] a.out - Spawn task
opts are: -(count) number of tasks, default is 1
-(host) spawn on host, default is any
-(ARCH) spawn on hosts of ARCH
-? enable debugging
-> redirect task output to console
-> file redirect task output to file
->>file redirect task output append to file
trace - Set/display trace event mask
unexport - Remove environment variables from spawn export list
unalias - Undefine command alias
version - Show libpvm version
pvm reads $HOME/.pvmrc before reading commands from the tty, so it can be used to customize the console environment, for example:
alias ? help
alias j jobs
setenv PVM_EXPORT DISPLAY
# print my id
echo new pvm shell
id
EXAMPLES
pvm
Starts up pvmd3 on the local host or connects to running pvmd3.
pvm hostfile
Starts up console and pvmd3, which inturn reads the host file and adds the listed computers to the virtual machine.
